No I totally agree the mc is doing his best and the dad is definitely a bad parent for what he's doing to him. I just appreciate that there's more motivation for the ml to prove that he's a better match for the mc, since it was kind of a fluke that he beat the mc and got to partner with him in the first place.
I'm kind of happy that the antagonist side character was made mc's new partner? I don't have anything against the ml and the mc should be allowed to partner with whoever he wants but it's always been a pet peeve of mine when the mc has a reputation for having high standards or being out of everyone's league or something and the ml pops up out of nowhere and almost immediately gets whatever he wants with almost no effort. I'm hoping the separation will be motivation for the ml to keep improving but it's staring to look like the mc's health issues are gonna guilt-trip-no-jutsu the dad/antag side character into accepting the ml as mc's partner.
